Flue thermostat dual circuit S0078 for ATMOS stoves

Product detailed description

The S0078 flue thermostat is a control component used in solid fuel heating systems, particularly in three-chamber stoves and pellet conversion models. It is installed in the control panel of the stove and is responsible for managing the operation of the combustion fan. This device is commonly found in residential and commercial heating systems where precise control of combustion air is required. Installers working on Atmos stoves will encounter this component during routine maintenance or replacement of control system parts.

Its role is to ensure that the fan stops operating once the combustion process is complete, preventing unnecessary energy consumption and potential overheating. This is especially important in systems where the stove is integrated with additional heat exchangers or ventilation components. The S0078 is designed for use in stoves with modifications for pellet burners, such as model 2017 (AD03), and in three-chamber models from 2012 onwards.

Technical parameters

Installation and connection

Installation of the S0078 involves securing the thermostat to the control panel of the stove and connecting it to the fan control circuit. The device is typically mounted in a fixed position and requires no additional adjustments. It is important to verify that the control panel is compatible with the dual-circuit design of the thermostat. Common installation mistakes include incorrect wiring to the fan circuit or failure to align the thermostat with the correct control panel slot. Always ensure that the stove is powered off before beginning installation to avoid electrical hazards.

Compatibility and accessories

The S0078 is compatible with a range of Atmos stoves, including DCxxSP(L), DCxxGSP(L), CxxSP(L), ACxxSP(L), and KCxxSP(L) models from 2012 onwards. It is also suitable for stoves with pellet burner modifications, such as model 2017 (AD03). It is important to note that the black wheel used on the control panel is not included in the package and must be ordered separately if required. No other accessories are included with the S0078, and no related products are listed for this model.

Technical background for designers

The S0078 operates by monitoring the combustion process and triggering the fan shutdown at the appropriate time. It is constructed using materials suitable for high-temperature environments and is designed to withstand the thermal stresses of repeated heating and cooling cycles. The dual-circuit design allows for integration with both primary and secondary combustion systems, ensuring that the fan is deactivated when the fuel has burned out. The efficiency of the device depends on the accuracy of the control signals and the stability of the electrical connections. Long-term performance is influenced by the quality of the installation and the condition of the control panel.

Service and operation

Regular inspection of the S0078 is recommended to ensure that it is functioning correctly. Key checkpoints include verifying that the fan stops after the fuel has burned out and that there are no signs of overheating or electrical faults. No specific service intervals are provided, but any visible damage or malfunction should be addressed immediately. The device does not require routine maintenance beyond visual inspection and basic electrical testing.
